八鋼煉輕燒鎂球的標準 Standard for Light-Burn Magnesium Ball of Bagang Steel

    八鋼的鎂球基本上以固廢為主原料制備的，其原料的特點限制了其生產的鎂球的成分，為了規范鎂球的生產工藝，實現有效的利用固廢和優化轉爐的煉鋼工藝，根據八鋼供應鎂球的主要供應商的生產情況，制定以下的標準;

技術要求 

    輕燒鎂球的化學成分及物理性能應符合下表的規定：

 SiO2 MgO Al2O3 C+S+P 水分 ≤8.0 ≥45.00 ～35 

不做要求 ≤1.00 

    粒度要求：20～50mm，其中小于5mm的粉末率不大于5%;抗壓強度:≥980KN/個，現場實測以從3米高度自由落體至水泥地面不碎裂為準。 3.3產品每批不超過500噸，必須取樣化驗送檢一次； 3.4每批取樣應不少于15公斤，并從各樣袋中均衡取樣。 

    輕燒鎂球的質量檢查和驗收應符合YB/T 5142的規定。 

    輕燒鎂球采用聚丙烯編織袋包裝，每袋1噸，保證內貨不外露，不撒漏，并標明產品名稱、供方名稱；每個批次都必須附有質量證明書。

    制定以上標準的主要依據如下 

1) 兄弟企業的技術標準和采購價格 

2) 鎂球的功能作用和定位 

3) 主要生產商能夠達到的質量水平

The magnesium balls of Bayi Iron and Steel are basically prepared from solid waste. The characteristics of the raw materials limit the composition of the magnesium balls produced. In order to standardize the production process of magnesium balls, the effective use of solid waste and the optimization of converter steelmaking The process, according to the production of the major suppliers of Magnesium Balls supplied by Bayi Steel, sets the following standards;

skills requirement 

The chemical composition and physical properties of lightly burned magnesium spheres should meet the requirements of the following table:

SiO2 MgO Al2O3 C + S + P moisture ≤8.0 ≥45.00 ～ 35

No requirement ≤1.00

Granularity requirements: 20-50mm, of which the powder rate of less than 5mm is not more than 5%; compressive strength: ≥980KN / piece, the actual measurement on site is based on the free fall from the height of 3 meters to the ground without cracking. 3.3 Each batch of products does not exceed 500 tons, and must be sampled and submitted for inspection once. 3.4 Each batch of samples should be no less than 15 kg, and samples should be taken from each sample in a balanced manner.

The quality inspection and acceptance of lightly burned magnesium balls should comply with YB / T 5142.

Light-burned magnesium balls are packed in polypropylene woven bags, one ton per bag, to ensure that the internal goods are not exposed and leaked, and the product name and supplier name are marked; each batch must be accompanied by a quality certificate.

The main basis for formulating the above standards is as follows

1) Technical standards and purchase prices of fraternal companies

2) Functional function and positioning of magnesium balls

3) The level of quality that major manufacturers can achieve
